well 'm finding the unit tangent bector and normal vector and then finding its curve, thats not bad but i'm hung up on some algebra..(adsbygoogle = window.adsbygoogle || []).push({});

I have sqrt(4t^2 + 4 + 1/t^2);

can that equal...

2t*2*1/t = 4?

Also...

sqrt(4t^2 + 25t^8)

Will that simpify too:

10t^5?
